    Abstract: A touch sensor according to an embodiment of the present invention includes a base layer, a first electrode layer including first dummy electrodes and first sensing electrodes including first holes therein arranged on a top surface of the base layer, the first sensing electrodes, an insulating interlayer formed on the base layer and covering the first electrode layer, and a second electrode layer including second dummy electrodes and second sensing electrodes including second holes therein arranged on a top surface of the insulating interlayer. An electrode visual recognition can be suppressed by an overlapping arrangement of the holes and the electrode patterns.

    Abstract: A touch sensor includes a driving electrode which includes at least two divided areas electrically separated from each other, wherein each divided area includes first patterns connected to each other in a first direction and second patterns extending from the first pattern in a second direction, and a receiving electrode which is formed on the same plane as the driving electrode in the second direction, wherein the driving electrodes are respectively connected to separate driving channels by driving electrode wirings for each divided area, such that it is possible to sense touch positions over the entire area only by a smaller number of channels. Thereby, it is possible to significantly reduce the bezel width, and may maintain excellent touch sensitivity while significantly shortening the touch recognition time.

    Abstract: A touch sensor includes a first sensing electrode unit formed on a substrate in a first direction and a second sensing electrode unit formed on the substrate in a second direction crossing the first direction. A plurality of micro-etched patterns are formed on a boundary of unit transparent electrodes constituting the first sensing electrode unit and the second sensing electrode unit. The unit transparent electrode has a shape in which a portion of a curve connecting vertices of a polygon is removed, and adjacent unit transparent electrodes are electrically connected to each other. It includes a segmental pattern dividing the first or second sensing electrode unit into two or more areas.
